Molecule 1 Air-Engineered 12" Memory Foam Mattress

So I've always used traditional mattresses but wanted to give memory foam a try. I did a ton of research and Molecule not only had great reviews but I was sold on their focus on quality sleep and recovery. Then I saw that Costco carried the brand and I ordered it right away! Before I got the mattress, I was worried memory foam would be too soft, smell weird, or be too "cooling". But my Molecule mattress really exceeded my expectations! It's firm and supportive. The cooling and breathability has been great for the summer. Plus everything is natural so no smells or airing out needed. Very happy with my purchase, just wished I switched earlier!

We have learned a number of things about bed purchasing. First price does not determine the quality, so paying more is not necessarily getting more. Second manufacturers ratings of firmness are not equal, every vendor is different. Third determine how you sleep, on your back, side, or stomach. That being said the Molecule is a well constructed bed, made of good materials, at a good price point. We did find the bed to be more firm than we liked as we sleep on our sides. We needed more pressure relief at our shoulders and hips. So we returned the mattress. Costco has great customer service and we had no issues with the return.

Sleeping much better with no backaches that I woke up with on my old Serta Quilt top mattress.
Was going to get a Sleep Number Bed but at over $7k and with some crazy exemptions you have to sign for before shipment (no return of base - $4k) it seemed ridiculous. The Memory Foam King was on special at Costco and it had good reviews so we ordered it and in 5 days it showed up at our door. Make sure you unpack it near your bed. It is heavy. It is very comfortable and we have had it for about two months now. When you sit on the side of the Foam Mattress it sags a little but that's to be expected with Foam. 4+ stars from me!

We bought a king size mattress to replace our full when we moved into our new house. We are approx 110lbs and 125lbs so I wanted something that wasn’t too firm as we are mostly side and back sleepers. This is a pretty firm mattress but it does mold pretty well to our bodies. I had some shoulder and hip pain the first week but it quickly went away and I find it to be really comfortable. My husband has always enjoyed the bed. Overall I do wish it was a tad bit softer but it’s worked out very well for us. We’ve had it for about a month so my hope is that we’ll break it in even more. Shipping was easy. We got our bed in about a week.

As soon as it was delivered, I opened the mattress up and let it fully expand. It took maybe half an hour to do so. There was no smell like other memory foam mattresses have so that’s a plus! The website claims it uses organic materials so there aren’t strong chemical odors.
I’m 5’2” and weigh about 140 pounds. Other reviews say that there were minor aches and pains when first sleeping on the bed. I’ll admit that I felt a few as well the first two weeks. The manufacturer states to give the bed at least a month to break in, but after the second week, I no longer felt any aches or pains. I love to sleep and this bed is like sleeping on a cloud! I think this bed is a great investment.

Do yourself a favor, and BUY this mattress!! It is the best mattress I have owned!! My lower back pain is gone, my hip pain is gone and due to an injury to my knee years ago, I was having a lot of stiffness and pain; and guess what? It is gone too!! But the best part and the one that I appreciate the most, sleeps cool and your body is cradled by this amazing mattress. Now, the only problem I have is, getting out of bed!! It is so soft and comfy that I have a hard time every morning leaving my bed. I would like to thank he engineers and athletes that designed and created this bed. You have done a marvelous job☺️

My husband and I wanted to love this bed, but in the end it was too firm. We had a standard firm bed before and were switching to memory foam in hopes it would form to our bodies better but still provide support. My husband in 6'8 & 260 lbs, so finding the right mattress has proven to be difficult, but even for him this bed was just as firm as our old spring mattress. Neither of us were sleeping soundly through the night, and I was still waking up with back and neck pain just as I was before. We ended up order the Casper mattress through Costco and found that was better for both of us. I do love that this bed has a lifetime warranty, and zero odor when you open as promised, just wish it was a bit softer.

Our last mattress was a Temperpedic. This mattress does not form to my body in the same way that the Temperpedic did. It feels like a very comfortable pillowtop mattress but when I lay on my stomach my arms fall asleep and that never happened on the old mattress. I like it fine, but I bought it as a replacement for a memory foam that I loved, and I may have made a mistake in this choice - it is memory foam, but doesn't act like it. When you compress the mattress top with your fingers it's clearly foam, but when you lay on it it's firm and does not act like memory foam. For the difference in price, it's worth keeping. This one is a fantastic value for the quality and comfort.
